WATER-COO LED COKE-OVEN DOOR.

SPECIFICATION forming part of Letters Patent No. 725,746, dated April 21, 1903.

Application filed July 9, 1902. Serial No.

To all whom 711 may concern.-

Be it known that I, EDWIN'A. Moons, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Water- Oooled Coke-Oven Doors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates, primarily, to cokeovens, has especial reference to doors for the ovens, has for its object increased durability of the doors, and consists in certain improvements in construction, which will be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification, Figure 1 represents a front elevation of the door detached; Fig. 2, a transverse horizontal section on line 2 2 on Fig. 1 and also showing. the hollow doorframe with door in the frame; Fig. 3, a front elevation showing the arrangement of watersupply pipes for connecting the doors in multiple or in a battery of ovens; Fig. 4, a like view of pipe connections for the door-frames; Fig. 5, alike view showing pipe for connecting doors in series; Fig. 6, a like view of pipe connections for door-frames in series, and Fig. 7 a detail view of one'of the flexible connections between the water-supply pipe and the door.

Reference being had to the drawings and the designating characters thereon, 1 indicates the hollow door, which is provided with two water-chambers 2 3, separated by a vertical partition 4, extending from the upper end of the hollow portion of the door nearly to the lower end thereof, forming a passage 5 below the partition for the circulation of water from one chamber to the other and reinforcing the door transversely to resist the intense heat to which it is exposed and prevent buckling or warping. The door is also provided with a water-inlet 6 and an outlet 7 and removable plugs 8 at the lower end of the chambers 2 3 for the removal of mud or other foreign solid matter.

9 is a flange surrounding the door, which flange projects inwardly and engages a non 14,ss a (No model.)

metallic seat 10, preferably of asbestos, on the outer face of the door-frame 11 and is held to its seat by a series of transverse bars 12, only one of which is shown, and a latch 13 for each bar.

The doors are secured in the door-frames 11 by a series of transverse brace-bars 51, only one of which is shown, each bar being secured to lug 52 by a rod 53, and the free end of the brace-bar is secured by a swinging latch 13, which engages the extension 54 of the bar. The bars are provided with setscrews or bolts 55, which engage the outer surface of the door to provide for any unevenness in the door or frame caused by warping, due to the intense heat to which the door and the frame are exposed, as fully shown, described, and claimed in another application for a patent filed herewith and serially numbered 114,882.

Each/door is provided with a bail 14, used for handling the door to insert and remove it from the door-frame.

The door-frame 11 is hollow, provided with water-circulating chambers 16 and 17, partitions 18 and 18', water-inlet passage 19 and outlet-passage 20, and is fully shown, described, and claimed in my application for a patent filed herewith and serially numbered 114,884.. p

The doors and the frames may be connected in multiple or in series, as desired. When connected in multiple, (see Figs. 3 and 4,) a pipe 21 supplies water to all the doors through flexible pipes 22, detachably secured to the doors by a suitable coupling 50, and the supply of water is controlled by valves 23, one for each pipe 22 and each door, and after the Water has circulated through the chambers of the door it is conducted through flexible connections .24., also detachably secured to the door, valve 25, and pipe 26; and water from pipe 21 flows through valve 27 and connections 28 into the door-frames, and after the water has circulated through the chambers in the door-frame it passes out through connection 29 and valve 30 into pipe 26. In this construction or connection of the doors and door-frames each door and door-frame is supplied with cold'water direct from the pipe 21. When connected in series, (see Figs. 5 and 6,) a pipe 31, provided with valves 32,

branches 32', having valve 33, and flexible connections 34:, detachably secured to the doors, supplies water, and after circulating through the chambers in the door the water passes out through flexible connections 35, also detachably secured to the doors, valve 36, and branch 37 into pipe 31; and Water from pipe 31 flows through valve 38 and connection 39 into the door-frame, and after flowing through its chambers passes out through connection 40 and valve 41 back into pipe 31. In this construction and connection of the doors and the door-frames the water supplied to the first of the series flows through all of them consecutively.

In either construction any door or doorframe may be out out of the water circulation by closing the valves connecting it to the supply and the discharge pipe.

When it is desired to remove a door for the insertion of a pusher to discharge the coke from the oven, the water-supply is shut off and the flexible connections 22 and 24 are detached from the door by the use of the ordinary hose-con pling 50, when the door may be removed. I

The door is provided with an opening 42 for the insertion of a leveling device and is supplied with a suitable cover. (Not shown.)

Having thus fully described my invention, what I claim is V 1. Ahollow,rectangular coke-oven door having communicating water-chambers therein, a vertical rein forcing-partition near the transverse center thereof extending from one end nearly to the opposite end, a water-passage between the end of said partition and the inner wall of the door, a water-inlet in one chamber, a water-outlet in the other chamher, and an opening in each chamber for the removal of foreign matter.

2. A hollow rectangular coke-oven door having communicating water-chambers therein, anda hollow rectangular door-frame provided with water-chambers; in combination with a supply-pipe, a connection between said pipe and the door, a connection between the supply-pipe and the door-frame, a dischargepipe, a connection between the dischargepipe and the door, and a connection between said pipe and the door-frame.

3. A hollow rectangular coke-oven door having communicating water-chambers therein, and a hollow rectangular door-frame provided with communicating water-chambers; in combination with a supply-pipe, flexible connections between said pipe and the door, a connection between the supply pipe and the door-frame, a discharge-pipe, a flexible connection between the discharge-pipe and the door, and a connection between said discharge-pipe and the door-frame.

In testimony whereof I affix my signature in presence of two witnesses.

EDWIN A. MOORE.
